High in the Sierra Madre mountains, criminal mastermind Thorne Devereaux has set up an underground manufacturing plant to produce an incredibly explosive substance: code name - PAID (Particle Accelerated Incendiary Device). Only a protective coating keeps it from exploding on contact with air. This compound is so unstable that an amount the size of a silver dollar could reduce a city block to smouldering ashes in seconds.

Devereaux must be stopped and there is only one man for the job: You... Nick Hunter! "
